Why am just being retarded about this name???

I am 12 weeks pregnant (due in December). If it's a girl, my husband and I planned to name the baby Brenigan DeLanie. Every time we tell someone that name their immediate response is "Oh that sounds Irish." That would be fine except for the fact that my husband and I both know that this baby was conceived on St. Patrick's Day, and it just creeps me out knowing that face and that we chose a name that everyone ociates with Irish (which we are not). Am I just being silly? Should we keep this name? Or should I consider other options for a girl since this name will probably irk me for my entire life?
